The shortcomings and prevention of graphite mold heat treatment process

Some related knowledge points of high pure graphite?

The applicable areas of high pure graphite include metallurgical, military, light industry, electrical battery industry, and fertilizer. It can be called high -purity graphite. In order to make more people familiar with it, here is some of the relevant knowledge points of Gao Chun graphite? I hope you can bring some better ones when you see it. Help.High -pure graphite is widely used in metallurgy, machinery, environmental protection, chemical, electronics, medicine, military, military and aerospace and other fields. Has high -purity, high -intensity graphite performance. In fact, the existence of graphite scales now makes graphite have excellent lubrication. Generally speaking, the larger the ordinary graphite scales, the better the lubricity. When we use it, we need to know that the graphite industry technology is still at a low level in the world. The products are mainly raw materials and initial processing products. Therefore, the high impurities of some products have limited its

Spherical graphite

Spherical graphite is a graphite product that is made from high-quality, high carbon natural flake graphite and uses advanced processing techniques to modify the surface of the graphite. It produces graphite products with different fineness, resembling elliptical spheroids.Spherical graphite material has good conductivity, high crystallinity, low cost, high theoretical lithium intercalation capacity, low and flat charge discharge potential. It is an important part of the negative electrode material for lithium-ion batteries and a replacement product for negative electrode materials used in foreign lithium-ion battery production. It has excellent conductivity and chemical stability, high charging capacity, long cycle life, and is green and environmentally friendly.The process of processing spherical graphite first involves roughly crushing, dressing, magnetic separation, and other processes in the spherical graphite workshop to form the initial product spherical graphite. Then, it ente

Why add graphite powder to glass fiber?

Glass fiber enhanced plastic (FRP) is a composite composite material based on synthetic resin. It has the advantages of light weight, high strength, corrosion resistance, microwave transmission, electrical insulation, and reasonable performance design according to requirements. It has been widely used in aerospace, petrochemicals, transportation, construction, shipbuilding, machinery, environmental protection, textile and other fields. Glass fiber enhanced plastic (FRP) has good electrical insulation property. Under normal circumstances, the amount of graphite powder is 2.5 ~ 5%, which can reach 30 ~ 50%. So why add graphite powder to glass fiber?From an economic and technological perspective, it is best to choose inorganic abrasive materials, so the amount of graphite powder in the abrasion -resistant material of the glass fiber reinforcement is relatively large. In short, glass fiber wear -resistant materials, because its matrix is a polymer material, fills solid lubricants and vari

Graph

Floating method is a type with less energy consumption and reagent consumption and low cost in the conventional purification method of minerals. Real limited improvement. For scales graphite, multi -segment grinding ore cannot be completely unbuttoned, but it is not conducive to protecting large scales of graphite. Therefore, the use of flotal methods to further improve the graphite quality. High carbide graphite with more than 99%must be pure graphite with chemical methods.(1) chloride roasting methodThe low roasting temperature and smaller chlorine gas consumption of chloride roasting method have greatly reduced the production cost of graphite. At the same time, the carbon content of graphite products is equivalent to the treatment of hydrofluoric acid method. Compared with the recovery rate of chloride and roasting method, because the chlorine gas is poisonous and has strong corrosiveness, it requires high requirements for equipment operations. It requires strict requirements. Seal

Heating graphite

Graphite radiator (3K-SBP) is a brand new heat-conducting heat dissipation material with unique grain orientation, which is evenly conducted in two directions. Improve the performance of consumer electronics. The product is uniformly dissipated while providing heat isolation in terms of thickness. The molecular structure diagram of the thermal graphite sheet is as follows:The unique combination of heat dissipation and thermal insulation performance of graphite heat conductive solutions allows heat -conducting graphite to become an outstanding material option for heat management solutions. The thermal graphite plane has the ultra-high thermal conductivity within the range of 150-1500 W/m-K.The chemical composition of Thermal Flexible Graphite Sheet is mainly a single carbon (C) element. It is a natural element mineral. The film polymer compound can obtain a graphized thin film under high temperature and high pressure because the carbon element is non -metal. Elements, but there is a co

Types of battery materials and its application areas

Lithium ion batteries are one of the currently widely used batteries in the market. The types of materials mainly include lithium cobaltate, lithium iron phosphate, lithium nickel cobalthocco, and lithium titanic acid. The advantage of lithium -ion batteries is that high energy density, high energy storage efficiency, long life, etc. The commonly used materials for nickel -metal hydride batteries are hydrogen anode and nickel oxide cathode. The advantage is that the use of safety, no pollution to the environment, and long life.A fuel cell is a battery that directly converts chemical reactions into electrical energy. The types of materials mainly include potassium hydroxide, sodium hydroxide, and sodium boric acid. Fuel cells have the advantages of low pollution, but their application scope is currently relatively limited. The types of sodium ion battery materials include sodium sulfide and sodium phosphate. The advantage of sodium ion batteries is that it is relatively cheap and long

Talk about the hazard factors before the use of graphite.

Talking about the dangers of the storage hazards before the use of graphite crickets, the harm of the natural environment of Graphite to the performance of the natural environment is accumulated over time, and the harm is very large. Generally, it is stipulated that it is stored in a natural environment that is clean and irritable. Let's put it on the fixed wooden shelf to support the molten aluminum graphite. Difficulty in transportation, although graphite has very good thermal resistance, it is a very very easy to crush object. In the whole process of application and transportation, it is necessary to pay attention, and it should not make it a serious injury and other conditions.The value in the sales market is not very high, in fact, it is wrong to think so. Graphite looks very simple, it is commonly used in installing a variety of liquid state. However, in the industry lacks it, it will have a very large problem. Except for the industry's chemical manufacturing industry, it is no
